the other day on my way home, I began to hear a belt squeel. i didnt think much of it since i knew that my ac belt wasnt connected properly. 2 minutes later, the car immediatly starts pinging. I pulled over and shut the car off immediatly.

So i tow the car home, and start taking her apart. timing belt looks fine (not shredded or falling apart), so i look on the ground and notice there is some drops of coolant on the floor. I take the water pump belt and pully off, the ac, the alt., the ps pump, all the accesories off. i start the car and it still pings.

I took the valve cover off, and everything seems to be ok in there (nothing is out of place, cracked, etc....).

i manualy turn the crank until the exhaust and intake cam marks are at 3 and 9 o clock. They line up perfect (put a ruler across and they are right in line).

what do I check now? It totaly sounds like my valves are hitting the tops of the pssitons.

HELP

What you hear is probably lifter tick. Was the car losing power when the noise started?

Goat Blower 06-28-2004 11:15 PM

Your cams line up with each other, but is the crank at TDC when the cams line up? Also did you pull the plugs to make sure one didn't crack and fall into a chamber?

b00stingsx 06-29-2004 03:17 AM

matt, I think it did in fact lose some power, but its hard to tell. I will check for the TDC and plugs sometime today. when i turn the two cams to 3 and 9 o clock, do i check the height of the pistons with somthing similar to a coat hanger in the cylinder to see if the crank is too at tdc?

The easy way is to check the mark on the crank pulley compared to the timing marks. That isn't 100% accurate, but is close enough to let you know if it is off. The real marks are on the crank, but harder to get at.

john 06-29-2004 10:47 AM

If you still have it apart, pull the timing cover off and check teh timing after lining up the crank sprocket. There is a mark on the pully which a metal piece points to. You can borrow my manual if you want. I believe it shows a pic.

where should these marks be in perspective to the cam gear marks?

When the cam gear marks are lined up, the mark on the crank pulley should line up with the timing belt cover at 0 degrees TDC.

Are the balance shafts still in the engine?

b00stingsx 07-05-2004 02:16 PM

ballance shafts are still in the engine.

b00stingsx 07-05-2004 02:52 PM

ok cam gears are lined up at 3 and 9 o clock. The crank pully is at "BTDC 10." is this correct/where it should be? did my timing jump?

b00stingsx 07-05-2004 02:56 PM

the car HAS had its valves done once already at around 110,000 miles. the car now has 154,000 miles. also, i the oil level was short 3 qts too (kinda weird since i DO check it everyso often). but i filled it up and started it and theres still a tick noise, so i turned it off right away.

Shane@DBPerformance 07-05-2004 03:00 PM

Make sure the dowels on the cam gears are at the top. Line the cam gear marks up, run a straight edge across the cam bolts and the marks. The straight edge should go through the center of the bolts. The mark on the crank pulley should be at TDC/0 BTDC.

b00stingsx 07-05-2004 04:06 PM

ok so heres the deal, timing looks right, 5 degrees before top dead center, it all lines up...

Car turns over without mpi fuse in, and DOES NOT make tick noise. THen when MPI fuse is in, the car starts, and makes tick noise. also it wont go over 4500 rpms.

Anyone?!

b00stingsx 07-05-2004 04:49 PM

i scraped the top of the pistons and they have dirty oily shit stuff on them, so im gonna get some combustion chamber cleaner and see what that does for me...

john 07-05-2004 07:40 PM

That dirty shit is carbon. Get MCCC to clean them. Are you still on the stock pump and the 550's?

b00stingsx 07-05-2004 08:24 PM

190lph and 550's. Where do I get mccc? the autoparts stores dont carry it at all (or anything like it)!

Also, what kind of oil pressure should i be getting?

john 07-06-2004 12:59 AM

I believe we got MCCC at Dodge. I think it stands for Mopar Combustion Chamber Cleaner making it a dealer only part. It got rid of my phantom knock last year. I am not sure about the oil pressure though. I still have my stock gauge.

b00stingsx 07-06-2004 03:06 AM

im thinking its a rod bearing now. I will pull the oil pan and hope that there aren't any metal shards just kick'n it in there!

joem 07-06-2004 08:39 PM

Like ecoli said the crank mark should be at 0 not 10 or 5. Sounds like you
:beer: jumped 2 teethon the belt like mine was.Lack of power knock and low compression.

b00stingsx 07-07-2004 03:32 AM

There are 4 marks on the timing cover, which one is zero though? There is a 10 mark but thats it. The other 3 marks arent numbered.

joem 07-07-2004 07:00 AM

the other side of 10. 10---?---?---0
joe

Pushit2.0 07-07-2004 09:09 AM

It is marked, for 15, 10, 5 and 0 TDC. clean off the plastic it probalby has dirt and what not all over it. Also were do you live I could come check it out after work tonight.

(763) 550-2962 I work 1pm-9pm.

b00stingsx 07-07-2004 12:18 PM

im in edina, tonight isnt good for me though. im gonna go check it to see if it lines up to the zero. I dont think it does...

b00stingsx 07-07-2004 03:23 PM

it did jump a tooth, is there a way to see if the valves are all bent? or are they bent for sure?

joem 07-07-2004 03:43 PM

If it jumped less than two tour good replace the belt water pump and tenc. and be done.

Engrish man, Engrish!!

If it just jumped one tooth you should be ok. If it jumped 2 teeth, then you may have problems. Over 2 teeth and you are almost definately in trouble. Check out the VFAQ's for items to buy.

Raptor 07-07-2004 09:03 PM

If you need me to I can come check it out with the boroscope to make sure there isn't valve to piston damage. Call the shop if you want more info. QPR that is.

b00stingsx 07-08-2004 01:44 PM

ok, how dirty is is supposed to be inside the timing belt cover. its reallly greasy and dirty? Can I just get a timing belt from checker or should I go to mitsu? How about a waterpump? just wondering because i get a deal through csk proshop, making things alot cheaper.

also, what is the procedure to line up all the timing marks since my belt jumped a tooth?

john 07-08-2004 04:46 PM

I would buy the parts through Mitsu. You may as well replace the water pump and maybe the tensioner while you are in there. How long has it been since your car has had a t-belt job? You might as well replace teh b-shaft belt or remove it.

As far as the oil and grease, you may need a seal on the front of your engine. Feel the seals on the front case and see if they are like plastic or rubber.
